Application ined December This invention relates to 'steam andv hot water heaters composed? of up-right'hollow` sections arranged face to face in sequence from front to rear andconstructed so as t0 vIn addition to thedesirabilityof making the heater symmetrical with reference to al longitudinal ver-tical center and incidentally, the use of' separate fire passages connecting the combustion chamber and iiue lat oppo" site'si'des of the said center, the main object is to provide separate sets of baffle plates, .one setfor each set of passages, movably and preferably: rotatably mounted therein` for regulating. vthe I effective capacity vof the pas'- j sages and. also. the. direction of flow lof the products of combustion from the combustion chamber to the flue.

' Another object is to utilize these baffle plates as a' means forxcleaning. the walls'of the passages from accumulations of' soot. or

other deposits i-'esultiiigI` from combustion of the fuel.

As illustrated, the'rock shafts '-22* and '-12.2k are angular in cross section while/,the holes in the batlie plates vfor receiving them are also of` angular cross section to .cause the corresponding set of baffle plates to turn with its shaft and at the' same time, permitting the shafts to be easily and quickly withdrawn from or reinserted intotheir respective sets of plates. s

several of the intermediate sections,iextend radially'equal distances V1n.,opposite directions' SO v of combustion from the combustion chamber "l Some of the plates as -23-, in thleimajor Vportions of the fire passages 7+ preferably from the rear section -V-3- forwardly through from their respective rock Y shafts V#252-- and A221.1 while other battle plates ,-232- in the remaining'tire passages -7- nearer the' front Vof the heaterextendinwardly and radially from one side only of their respective shafts thereby leaving the outer portions ofthe fire'p'assages open for the, direct upward passage of the productsof combustion around the Voutside of the baffle plates 23-- from the combustion chamber to corresponding sides of the flue -10-.

In other words, the baffle plates *234- are l of substantially `the same area asthe. cross sectional area of their respective'fre passages 1'-, while the area of the remainingbaliie plates '23--y i-s substantially equal to vhalf the cross sectional'area ofthe corresponding tire passages --7--,l and it therefore, follows that when the. baffle plates are in their maximum closedpositions, the'productsof combus'- tion rising from the rearfof thecombustion chamber will be caused to'travel forwardly through a considerableportion of the area of the combustion chamber and thenceV upwardly around the outer Vends of thebaftle plates -23- to opposite sides of the` overlyingportions of the flue lO- and thence rearwardly through the said Aflue to 'the f smoke pipe -18-. ,Y I.

Y L*It is evident, however, that the vturning of eitherof vthea'rock shafts 'and' their corresponding bafflek plates from their normal closed positions, will vary the effective capacity-,of the ,corresponding lire passages A1,635,404 f 1 vg3 and' may also aect the direction of the How of the products of combustion from the combustion chamber to the flue -10-.

For example, by turning either set of batiles a quarter-turn will permit the major portion of the products of combustion to pass -from the combustion'chamber through the corresponding passages 7 and directly to the adjacent side of thevflue providing lthe opposite set of baille plates remain 1n' their horizontal positions as shown inFigs 3 and 4.

`plates upon their respective rock shafts and within the corresponding lire passages isito utilize their rotary movement in cleaning the walls of said passages from soot and other deposits resulting from combustion of the fuel thereby greatly expediting the interchange of heat from the products o combustion tothe water inthe several sections and materially increasing the efficiency of the heater. Y I

The operation of our invention will now be readily understood upon reference to the foregoing description and' the accompany.,` ing drawing and itis evident that various changes may be made in the detail construction and arrangement of the various parts of y the heater without departing from the spirit of this inventionry Weclaim: F

1. A water heater comprising an'upright shell having a combustion chamber and a smoke flue' above the combustion chamber and both extending from the vfront wall-*to the rear wall-of the shell, said shell having separate upright fire passag'esconnecting` opposite sides of the combustiony chamber with v i corresponding sides of the smoke flue, parti- Another object in mounting theseA baille tions extending vertically between the top of the combustion chamber and bottom of the smoke flue and between opposite upright fire passages, and baffle plates rotatably mounted in said firepassages at opposite sides of.

the partition for regulating the passage of the products of combustion from the com- 'g bustion chamber .to the smoke flue. Y

2. A water heater as in claim 1 in which the baffle plates at each 'side of the partition are connected for simultaneous operation.

In witness whereof we have hereunto set our hands this 11th dayo1 December, '1928.
